摘　　要：在诸多同步电机启动方式中,自控变频软启动方式是技术含量最高,性价比最优的启动方式,是同步电机软启动技术的发展方向。针对无位置传感器的自控变频式同步电机启动系统中的低速转子位置检测,加载启动,准同期并网等几个关键问题进行理论分析和实践验证,并在抽水蓄能电站实验装置上进行测试,取得了很好的启动效果。In many ways of synchronous motor starting,automatic control variable frequency soft starting is thedevelopment direction of synchronous motor soft starting with the highest technology and performance. The problemsinvolved in automatic control variable frequency soft starting device without position sensor,such as rotor positiondetectionis during low speed,starting with load,quasi-synchronization grid connected control,were analyzed andstudied in practice. It worked perfectly on a model of pumped storage power station.
